What should I do to avoid catching a cold or the flu?

Cold weather weakens the body's immune system, creating favorable conditions for cold and flu viruses to spread. Several measures can reduce the risk and prevent these seasonal infections.

When the weather turns to winter, the amount of sunlight reaching the ground decreases. Without enough sun exposure, the skin won't produce enough vitamin D. A lack of vitamin D will prevent the immune system from functioning effectively, according to the health website Healthline (USA).

Sneezing is a common symptom of both the flu and the common cold.

Furthermore, cold, dry winter weather can weaken the mucous membranes in the skin, nose, eyes, and lungs. As a result, bacteria and viruses can more easily enter the body. To prevent colds and flu when the weather turns cold, people can apply the following methods:

Wash your hands frequently.

Washing your hands frequently with soap will help remove cold and flu viruses. This simple habit will help prevent the spread of viruses, especially after touching surfaces such as doorknobs, tables, chairs, or items in hospitals and office buildings.

Eat a balanced diet.

Eating a balanced diet provides essential nutrients for the immune system. Plant-based foods like oranges, tangerines, guavas, leafy green vegetables, and nuts are rich sources of vitamins C, D, E, and zinc. All of these contribute to immune enhancement.

Drink plenty of water.

Cold winter temperatures are often accompanied by dry air. This can cause dryness of the skin, nasal mucosa, and eyes. Therefore, drinking enough water helps maintain moisture in these areas. In particular, maintaining moisture in the nose and lungs can help reduce the risk of respiratory infections.

Use a humidifier.

Using a humidifier is an effective way to help maintain humidity in your home. Good air humidity levels can help reduce respiratory irritation, making it easier to breathe for those with colds or flu, and reducing sore throats.

Get enough sleep.

Everyone should ensure they get 7 to 8 hours of sleep each night. Lack of sleep not only reduces concentration and causes fatigue, but also weakens the immune system.

Maintain physical activity.

Regular exercise improves blood circulation and immune function, thereby reducing the risk of catching colds and the flu. If the weather is too cold, people should prioritize indoor exercises such as yoga, stretching, or gym workouts, according to Healthline.
